Hi, there,
I'm new to floatcanvas and wonder if I'm on the right way,
here are my codes which are very similar to the simple line
drawer in the floatcanvas2 demo.
class LinesDrawer(object):
def __init__(self, canvas):
self.lines = None
self.canvas = canvas
canvas.subscribe(self.onLinesBegin, 'input.left_down')
canvas.subscribe(self.onLinesDrag, 'input.move')
canvas.subscribe(self.onLinesEnd, 'input.left_up')
def onLinesBegin(self, evt):
startPnt = evt.coords.world
self.lines= self.canvas.createLines( [startPnt, startPnt], look =
('red','white'))
def onLinesDrag(self, evt):
if self.lines is None:
return
endPnt = evt.coords.world
self.lines.model._setPoints(numpy.vstack([self.lines.model._getPoints(),endPnt]))
self.lines.model._setDirty(True)
def onLinesEnd(self, evt):
self.lines = None
Thanks
Miles
